  • Hydrostatic linear drive system
    Patent number: 11035391
    Abstract: A linear drive system, in particular for a closure unit of a blow mold installation, with a simpler and more compact structure, a higher retraction and expansion speed in rapid mode, higher forces in power mode, and reduced energy consumption, than the prior art includes a cylinder arrangement which brings about a retraction and extension movement in rapid mode by separate hydraulically active faces which are independent of a larger hydraulically active face which is acted on with pressurized hydraulic fluid only in power mode. During the extension movement in power mode, however, the hydraulically active faces cooperate which contributes to high forces with a compact structure of the drive system.
    Type: Grant
